Specific embodiment
Fig. 1 shows a kind of normal axomometric drawing of embodiment of the operating element compensating abrasion for clutch.Here,
Do not limit general in the case of, for following description assume by means of operating element manipulate clutch be " normally closed " type
Clutch, it is arranged on the right side of the operating element shown in Fig. 1.The manipulation of clutch, that is its open real by push rod 2
Existing, in order to manipulate or holdback clutch, this push rod 2 moves towards manipulating direction 4.
Operating element or its part are described below together with the exploded view of Fig. 2, its more properly shown partially in manipulator
All parts present in part.Clutch is manipulated by push rod 2 and this push rod 2 manipulates further through drivening piece 6, and push rod 2 is borrowed
Help this drivening piece to move on manipulation direction 4 and on the direction contrary with manipulating direction 4.For this purpose, drivening piece 6 can
In the direction of motion 4 and the direction contrary with the direction of motion 4 support can around axle 8 rotatably and rotatably.Here, hereinafter term
" manipulation direction " synonym ground is used for the translational motion of push rod 2 and the rotary motion of drivening piece 6, such as available according to Fig. 1
Both motions like that correspond to each other.For power transmission described in detail below, drivening piece 6 has cylindrical peripheral face 10.Tool
The coiled springs 12 of multiple turns are had to arrange around the side face 10 of drivening piece 6.Here, in ordinary meaning, coiled springs
It is interpreted as a kind of layout of spring mode of winding, its multiple coaxial turn is adjacent one another are in the axial direction and its work
Principle is based on, the interior diameter alterable of turn, thus can with the object being arranged within coiled springs, here be drivening piece
6 set up power transmission connection and can be separated.
Coiled springs 12 are respectively provided with an end in the end of its turn, i.e. first end 14 and the second end
